    Wherever computers are commonplace, free online mapping systems such as MapQuest and Yahoo! Maps are among the Web's most popular reference sites. Consumer sites such as these compete to improve their interfaces and data relevance to better appeal to the browsing public. But innovation in online mapping isn't limited to these household names. Three trends dominate online mapping today: 1) the brin... View full abstract»

    In this article, we reiterate the characteristics that make the rainbow color map a poor choice, provide examples that clearly illustrate these deficiencies even on simple data sets, and recommend better color maps for several categories of display. The goal is to make the rainbow color map as rare in visualization as the goto statement is in programming - which complicates the task of analyzing a... View full abstract»

    Since their inception over three decades ago, the fields of computer vision, image processing, and computer graphics have been concerned with analyzing, manipulating, and synthesizing images using numerical algorithms. While these three fields continue to evolve in a loosely coupled manner, users' near-ubiquitous access to digital cameras and personal computers has spurred renewed interest in what...

    In this article, we develop tools for shadow modification in images where a shadowed region is characterized by soft boundaries with varying sharpness along the shadow edges. Modeling shadow edges presents an interesting challenge because they can vary from infinitely sharp edges for shadows produced by a point light source to extremely soft edges for shadows produced by large area light sources. ...

  • Optical Splitting Trees for High-Precision Monocular Imaging

    In this article, we consider the design of monocular multiview optical systems that form optical splitting trees, where the optical path topology takes the shape of a tree because of recursive beam splitting. Designing optical splitting trees is challenging when it requires many views with specific spectral properties. We introduce a manual design paradigm for optical splitting trees and a compute...

  • Exploring Defocus Matting: Nonparametric Acceleration, Super-Resolution, and Off-Center Matting

    Defocus matting is a fully automatic and passive method for pulling mattes from video captured with coaxial cameras that have different depths of field and planes of focus. Nonparametric sampling can accelerate the video-matting process from minutes to seconds per frame. In addition, a super-resolution technique efficiently bridges the gap between mattes from high-resolution video cameras and thos... View full abstract»

    Simulation-based training using VR techniques is a promising alternative to traditional training in minimally invasive surgery (MIS). Simulators let the trainee touch, feel, and manipulate virtual tissues and organs through the same surgical tool handles used in actual MIS while viewing images of tool-tissue interactions on a monitor as in real laparoscopic procedures View full abstract»

    Laplacian instability is the physical mechanism driving pattern formation in many disparate natural phenomena. Current algorithms for simulating this instability are slow and memory intensive. A new algorithm, based on the dielectric breakdown model from physics, is more than three orders of magnitude faster than previous methods and decreases memory use by two orders of magnitude. Our algorithm a... View full abstract»

    A computer system for interactively creating marbling textures is built on the physical model of the traditional marbling process. The approach generates marbling designs as the result of color advection in the 2D flow fields obtained by numerically solving the Navier-Stokes equations on the GPU with a multigrid solver View full abstract»

    Mobile gaming is one of the fastest growing segments in the video game industry. Through a partnership between Motorola Laboratories and GamePipe Laboratory at the University of Southern California, we are exploring Linux's capabilities for mobile gaming and to provide developers with an alternative to what is predominantly a Java-based medium. Moving beyond Java lets game developers fully leverag... View full abstract»
